Abstract (en)
[origin: EP0881437A2] The flow passage not occupied by the plates (14) of the heat exchanger is formed by a gap (22) provided between the heat exchanger and wall (20) of the combustion chamber (10), and if necessary this gap is covered by a push-in element. The latter element is a U-shaped piece of curved metal sheet, the sides of which lie on the combustion chamber's wall and on the plates as a spring fit. The crosspiece connecting the sides lies at an acute angle to the side lying against the combustion chamber wall.
